Abstract

Maggot menjadi trend usaha rumahan karena mudah dilakukan dan biaya yang murah. Selain bernilai ekonomis, usaha maggot memiliki dampak yang baik bagi lingkungan, khususnya pada penanganan masalah sampah organik terhadap lingkungan. Potensi utama dari budidaya maggot adalah ketersediaan sumber pakan dan permintaan pakan ternak dari maggot. Adapun salah satu usaha budidaya maggot dilakukan oleh Magot Mulia Mandiri di Desa Pematang Johar. Dalam menjalankan usahanya, Magot Mulia Mandiri menggunakan sampah organik pasar dan rumahan yang dicincang secara manual dengan pisau untuk pakan maggot. Hasil pakan yang diperoleh dari sampah organik ini bersifat kasar dan keras sehingga sulit dikonsumi dan dicerna oleh maggot. Dampaknya, maggot yang dihasilkan berukuran relatif kecil karena penyerapan nutrisi yang tidak optimal dan nafsu makan yang menurun. Sifat makan Maggot dilakukan dengan cara menghisap sehingga diperlukan pakan yang lembut. Pakan yang lembut dapat diperoleh dengan menggiling sampah organik menggunakan mesin pembubur, namun hal ini belum dilakukan oleh pembudidaya maggot. Oleh karena itu, tujuan dari kegiatan ini adalah untuk melatih mitra dalam memproduksi pakan mandiri maggot menggunakan mesin pembubur agar diperoleh pakan yang lembut. Metode pelaksanaan menggunakan Teknik presentasi, tanya-jawab, diskusi, demonstrasi, dan unjuk kerja. Hasil kegiatan diperoleh pakan maggot yang lembut sesuai kebutuhan, sehingga dapat diberikan tanpa harus melalui proses fermentasi. Pada aspek hasil pelatihan terhadap kualitas kegiatan pelatihan diperoleh nilai rata-rata 3,77 dan tingkat pengetahuan mitra memperoleh nilai rata-rata 3,80 dari nilai maksimum 4,00. Hal ini menunjukkan bahwa kualitas kegiatan dapat dikatakan baik dan terdapat peningkatan pengetahuan mitra dalam budidaya maggot. Terjadi peningkatan juga pada aspek keterampilan peserta berdasarkan hasil observasi dan produk yang dihasilkan, dimana peserta dapat memproduksi pakan menggunakan mesin pembubur.

Abstract

Analisis isi lambung ikan red devil (Amphilophus labiatus) di Danau Toba bertujuan untuk mengetahui jenis makanan dan dampak yang ditimbulkannya sehingga diketahui risiko invasif yang ditimbulkan di Danau Toba. Penelitian dilaksakan pada bulanFebruari April 2025. Metode yang digunakan yaitu metode survey, dimana penentuan tiga lokasi penelitian dilakukan secara purposive sampling (Kecamatan Porsea Kab. Toba, Kecamatan Muara Kab. Tapanuli Utara, Kecamatan Onan Runggu Kab. Samosir). Sebanyak 25 sampel red devil dikoleksi di masing-masing lokasi. Hasil penelitian yang diperoleh menunjukkan bahwa morfologi ikan red devil terdiri dari 3 warna yaitu merah atau oranye, merah campur hitam dan hitam. Identifikasi panjang relatif usus (RGL) menunjukkan ikan red devil dimana bersifat omnivora. Jenis makanan yang terdapat di lambung ikan di dominasi oleh fitoplankton sebagai makanan utama, zooplankton sebagai makanan pelengkap, terdapat perbedaan di lokasi Porsea yaitu zooplankton dan tulang ikan berperan sebagai makanan pelengkap, jenis makanan tambahan seluruh lokasi sampel yaitu terdiri dari ikan kecil, potongan daun, potongan akar, sisik ikan, lumut, sementara lokasi II dan III tulang ikan sebagai makanan tambahan red devil di Danau Jenis makanan yang diidentifikasi berbeda di tiap lokasi tergantung ketersediaan makananan di tempat dia hidup. Risiko invasif dari ikan red devil Danau Toba yaitu sebagai menyebabkan kompetisi makanan tinggi juga memangsa anakan ikan lain sehingga ikan lain sulit berkembang. Adaptasi tersebut menyebabkan ikan red devil cepat mendominasi wilayah perairan dan menyebabkan ikan lain punah serta sulit dikendalikan populasinya.

Graphical Abstract Highlight Research 1. Tor tambra is the most dominant species other Tor species in Aceh Province, Indonesia. 2. The population of T. tambra has decreased significantly due to overfishing and environmental destruction. 3. This research aims to examine the habitat characteristics, growth patterns and condition factors of T. tambra. 4. Analysis of the length weight relationship of T. tambra revealed that the condition of the fish was stable . Abstract This research was aimed to examine the habitat characteristics, growth patterns and condition factors of T. tambra in the Mamis River, Leuser Ecosystem Area, Aceh, Indonesia. This research was conducted on the Mamis River in three different river conditions from July to August 2023. The ecological parameters of T. tambra were conducted by observing the main, broodstock, spawning, and nursery ground habitats based on diversity of catch size at a location, water quality, aquatic substrate, aquatic vegetation, and water shade. The growth pattern parameter was also analyzed to reveal the condition of T. tambra.  The T. tambra habitat in the Mamis River includes broodstock and spawning habitat with the criteria from small to large rocks overgrown with Bryophytes, gravel and sand substrates, clear water color, slow to swift water currents, and river environment most of it is primary forest. In the main habitat, there is dominant riparian vegetation in the form of forest timber trees such as Pometia pinnata, Ficus fistulosa, Hydnocarpus castanea, and Aglaia tomentosa. The habitat for the juvenile is in the form of rocks, gravel substrate, clear water color, and fast water currents. In the nursery habitat, the dominant riparian vegetation is Balakata baccata. Based on the results of water quality analysis at the three stations, it shows that temperature, pH, DO, currents, BOD, COD are significantly different, but brightness levels are not significantly different. Based on the analysis of the length-weight relationship, it shows that the condition of the fish is stable with sufficient food availability.

Abstract

This study was conducted to determine the effect of water salinity changes on methionine content in tiger grouper juvenile (Epinephelus fuscoguttatus). A total of 2,560 tiger grouper juveniles were used and divided into five groups consist of 1 control group (without exposed to salinity changes) and 4 treatment groups. The salinity was changed every 2, 3, 4, and 6 hours in treatment A, B, C, and D, respectively. Salinity levels were changed during 24 hours by lowering salinity level from 32 psu to 22 psu. Twenty five of fish were collected from each treatment for methionine content analysis. Data were analysed using one way analysis of variance (ANOVA). The results showed that there was a decrease in methionine content in all treatments. A significant decrease (P0.05) of methionine content in treatment A, B, and C were observed after 20 hours (1.15%), 18 hours (1.27%), and 16 hours (1.24%), respectively. While at 0 hours (control), the methionine content was 2.02%. Methionine level in treatment D was not significantly different (P0.05) compared to control group. As conclusion, rearing the tiger grouper juvenile with salinity fluctuations every 6 hours did not lead to methionine deficiency.

Abstract

The threat of decreasing populations of Tor species continues to increase due to intensive fishing, habitat destruction and infrequent cultivation efforts. Monitoring of this group of fish must be carried out routinely to reveal the population conditions of fish. This research aims to reveal the population conditions of fish through an analytical approach to the length-weight relationship and fish otolith size. All fish samples were then taken for otoliths to measure their size and analyzed further using a scanning electron microscope (SEM). The research was conducted in the Tangkahan River, North Sumatra, Indonesia from January-March, 2023. The results showed that 43 samples of T. douronensis, 34 samples of T. tambra, and 24 samples of T. tambroides had b values of 2.853, 2.757, and 2.353, respectively. The b value in this study indicated that the fish had a negative allometric growth pattern. The size of the otoliths of the three Tor species shows that T. tambra has the highest length (the distance measured from the anterior to the posterior of the of sagitta otolith) on average reaching 9.31 mm, while T. tambroides and T. douronensis only reach 1.53 mm and 1.83 mm. The results were confirmed by ANOVA showing significant differences (P 0.05) in the mean value of otolith size based on Tor species, where the otolith size of T. tambra was significantly different compared to the other two species. The condition of Tor species in the Tangkahan River has experienced ecological pressure. This indication was concluded from the results of the analysis of the length-weight relationship of fish which showed b value 3 (negative allometric). The results show that the characteristics and size of the otoliths can differentiate Tor species and facilitate identification efforts related to management and conservation.Keywords:Habitat DestructionNegative AllometricAnterior of Sagitta OtolithPosterior of Sagitta Otolith

Abstract

The increasing occurrence of introduced fish species in Lake Toba highlights the need to investigate their reproductive biology and condition factor to understand their invasive potential. This study aimed to analyze the reproductive biology and condition factor of Tiger Barb (Puntigrus partipentazona) in Lake Toba. The study was conducted from January to March 2026 at three sampling stations in Pangururan District using a survey method with purposive sampling. Data were collected through fish trapping using fish traps, water quality measurements, morphological observations, reproductive biology assessments, and laboratory analysis of condition factor. The results showed that P. partipentazona exhibited gonadal maturity stages (GMS) I - IV. The female gonadosomatic index (GSI 0,046 – 0,090%) was higher than that of males (0,006 – 0,020%) at all stations. The length at first maturity was greater in females (47,58 – 56,89 mm) than in males (42,81 – 46,13 mm). Fecundity ranged from 194 - 361 eggs and was positively correlated with body length and weight. Sexual dimorphism was observed in body coloration and shape. The condition factor ranged from 0,97 – 1,32, indicating good physiological condition and a favorable environment for growth and reproduction. These findings indicate a high adaptive potential of P. partipentazona in the Lake Toba ecosystem.

Abstract

White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.
